1992 and 1996 Chinese Nuclear Blasts
recorded by over 400
USGS
seismic stations world-wide. These data are animated on global maps and
transparent spheres and display the spreading seismic wavefront as it arrives at each station,
following the leading edge of the P phase arrivals as the signal travels around the world.

SMU EarthQuake imagery
and animations generated from
USGS and
ISC seismic records, the
GERESS array, the SMU
TXAR array and the SMU Surface Wave Impulse Generator
deployed by D. Craig Pearson of the Los Alamos National Laboratory.
This set of visualizations explores various methods
of viewing time-dependent seismic signals as objects and sets of objects.
